DETAILED DESCRIPTION

While this invention is susceptible of embodiment in many different forms, there is shown in the drawings and will herein be described in detail preferred embodiments of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the broad aspect of the invention to the embodiments illustrated.

Referring to FIGS. 1-5, disclosing an embodiment of the present invention, there is shown a foldable, door-hanging ironing board assembly 10 which includes an ironing board 12, a frame 14, a lower support member 16, a latching assembly 18, and an ironing board biasing assembly 19.

The frame 14 has a left frame member 20, a center distal member 22, a right frame member 24 and a cross cylindrically-shape, tubular, member 26. In the embodiment shown in FIG. 1, the left frame member 20, the center distal member 22, and the right frame member 24 are formed from a single piece of tubular steel. The single piece of tubular steel has two semi-circular bends 28, which are bent to form approximately right angles between the left frame member 20 and the center distal member 22 and between the right frame member 24 and the center distal member 22, essentially forming a U-shaped frame. In an alternative embodiment, the frame 14 can be formed using separate pieces for the left frame member 20, the center distal member 22, and the right frame member 24. In this embodiment, the left frame member 20, the center distal member 22, and the right frame member 24 can be attached to each other using any suitable method, including nuts and bolts or welding.

The cross cylindrically-shape, tubular, member 26 is pivotally mounted between the left frame member 20 and the right frame member 24, on the ends of the left frame member 20 and the right frame member 24 opposite the ends where left frame member 20 and the right frame member 24 connect to center distal member 22, and located near the proximal end of frame 14. In the embodiment shown in FIG. 1, the left frame member 20 and the right frame member 24 each have a cylindrically shaped attachment tube 30, which are configured to telescopically receive the ends of cylindrically-shape, tubular, cross member 26, for pivotal rotation therein. The attachment tubes 30 can be configured to mate with the curved outer surface of the left frame member 20 and the right frame member 24 and secured to the curved outer surface of the left frame member 20 and the right frame member 24 as with a weld. The left frame member 20 and the right frame member 24 can be secured together as in known in the art, effectively capturing the cross member 26 within the attachment tubes 30.

The frame 14 further includes a foot member 31 secured to the end of the left frame member 20 and the right frame member 24. Each foot member 31 is configured to slide over, and fit upon, the end of the left frame member 20, and the right frame member 24, such as each member having a cylindrical bore to telescopically receive the cylindrical ends of members 20 and 24. The foot member 31 is formed to have a protuberance 33 which extends inward from the left frame member 20 and the right frame member 24, and has a flat bottom which allows each foot member 31 to rest against a flat surface, such as a door. Each foot member 31 is preferably constructed from plastic or a rubber-like material.

The ironing board 12 is embodied as a typical ironing board with a generally rectangular proximal portion 32 and a generally narrowing distal portion 34, such as a narrowing nose, the proximal portion 32 being moveably mounted, preferably pivotally, at a lower end of the frame 14 and supported by a guide assembly 36. However, those skilled in the art will recognize that any shape of ironing board can be used. A cover 38 fits over the ironing board 12 and includes a binding (not shown), including but not limited to a bungee cord, elastic, or drawstring, positioned around the perimeter of the cover 38 for securing the cover 38 to the ironing board 12. The cover 38 can be made of cotton as known in the art, or can be made from material with burn/scorch resistant characteristics, such as disclosed in U.S. Pat. No. 5,566,481. In other embodiments, the cover 38 includes multiple layers of materials, including but not limited to a layer of foam padding.

The ironing board 12 includes a frame, the proximal end 39 of which can be seen in FIGS. 1, 2, 2B, and 4, that defines the outer edges of the ironing board 12. The frame is preferably formed from square metal tubing, but could be formed from any material that gives the ironing board sufficient rigidity.

The guide assembly 36 includes a left track 40, a right track 42, a plurality of cross supports 44, a guide 46 and a rod 48. The guide 46 has a lower support member 16 which is fixedly connected at one end to cross cylindrically-shape, tubular, member 26. The connection between lower support member 16 and cross cylindrically-shape, tubular, member 26 can be made by a weld, or any other suitable fastener, such as a bolt and nut. The opposite end of the lower support member 16 is fixedly attached to the rod 48. The connection between lower support member 16 and the rod 48 can be made by a weld. In an embodiment, the connection between the lower support member 16 and the rod 48 can be reinforced by plate 50.

A guide follower 52 is attached to each end of the rod 48. Each guide follower 52 is sized and shaped to fit within the left track 40 and the right track 42, and is configured to slide within the left track 40 and right track 42. Each guide follower 52 is preferably formed from plastic, but they can be formed from any suitable material that allows them to slide within the left track 40 and the right track 42.

The latching assembly 18 has a latch 54 that is preferably formed from a steel rod which has a first leg 56 and a second leg 58. The first leg 56 and the second leg 58 are formed by bending the rod at approximately a right angle a third of the way down its length. The second leg 58 is inserted through holes in the left track 40 and the right track 42, and extends through the rails 40 and 42. The second leg 58 is secured on the rear surface of the right track 42 with a clip.

The latch assembly 18 further includes two latch pawls 60 and 62 that are fixedly attached to the second leg 58 of the latch 54, preferably by a weld. One skilled in the art will appreciate that other means of attaching latch pawls 60 and 62 to the second leg 58, without departing from the scope of the present disclosure. The latch pawls 60 and 62 are sized and shaped so that when the ironing board 12 is in an unfolded position (which is described more fully below), a lower arm 66 of each latch pawl 60 and 62 engages the rod 48 of the guide assembly 36.

The latch assembly 18 also includes a load spring 64. A first end of the load spring 64 engages with an upper surface of the right track 14. The load spring 64 wraps around the second leg 58 of the latch 54 and has a U-shaped termination, which is sized and shaped to engage latch pawl 62. The latch assembly 18 is configured to maintain ironing board 12 in the unfolded position described below.

A latch rod 65 extends from an inner edge of the ironing board 12 frame, through holes in the left track 40 and the right track 42, and extends through the rails 40 and 42, to the opposite inner edge of the ironing board 12 frame. The latch rod 65 is fixedly attached to each inner edge of the ironing board 12 frame, preferably by a weld.

The ironing board biasing assembly 19 includes a pivot rod 66 attached as by welding to the proximal end 39 of the ironing board 12. The pivot rod 66 pivotally mounts ironing board 12 to the frame 14. The left frame member 20 and the right frame member 24 each have a hole (not shown) drilled into their inner surfaces, which holes each receive a hollow, cylindrical, collar 68 and 70, as by a press fit into the holes. The collars 68 and 70 have an inner diameter that is greater than the outer diameter of pivot rod 66, allowing pivot rod 66 to rotate therein within the collars 68 and 70.

The biasing assembly 19 includes biasing elements, disclosed as torsion springs 72 and 74. Prior to securing the cross cylindrically-shape, tubular, member 26 to the left frame member 20 and the right frame member 24 of frame 14 with the connecting rod, as described above, the torsion springs 72 and 74, are mounted onto the pivot rod 66 by sliding the pivot rod 66 through a coil 75 of each of the torsion springs 72 and 74. The ends of the pivot rod 66 are then inserted into the hollow, cylindrical, collars 68 and 70. Once the cross cylindrically-shape, tubular, member 26 has been secured to the left frame member 20 and the right frame member 24 with the connecting rod, the pivot rod 66 is captured within the hollow, cylindrical, collars 68 and 70.

The torsion springs 72 and 74, each include an upper arm 76 that extends from a first end of the coil 75 into a “C” shaped finger 77. Finger 77 terminates into a claw 78 to frictionally engage with the ironing board 12 frame, here shown engaging with the proximal end 39 of the ironing board 12 frame. The inside surface 79 of the wall of the ironing board 12 frame has a curved recess 79 a. The recess 79 a is configured to receive the claw 78, and preferably part of the finger 77, to enhance engagement with the ironing board 12. With such engagement the upper arm 76 biases against clockwise movement of the ironing board 12, as viewed in FIGS. 2A, 2B and 2C, of the frame of the ironing board 12. A lower arm 80 of each of the torsion springs 72 and 74 extends generally downwardly and generally parallel with the left frame member 20 and the right frame member 24, respectively, of frame 14. Arm 80 bends at approximately a right angle into finger 81. Each finger 81 fits into a bore 84 in the left frame member 20, and bore 86 in the right frame member 24, respectively. With such engagement that the lower arm 80 of each of the torsion springs 72 and 74 biases against clockwise movement of the ironing board 12, as viewed in FIGS. 2A, 2B and 2C, of the ironing board 12.

The foldable, door-hanging ironing board 10 further includes a plurality of mounting hooks 86. Each mounting hook 86 has a unitary “U” shaped first end 88, which is formed by first bending the first end of the mounting hook 86 at roughly a right angle to form a first leg 90, and then making a second generally right angle bend to form a second leg 92. The second leg 92 then bends at about a 90° angle into the main longer body 93. Together, the leg 90, leg 92 and the part of the body 93 alongside leg 92 generally form a “U” shape sized to receive the upper end of a door. The dimensions of the “U” shaped first end 88 are chosen so that the “U” shaped first end 88 fits over a standard door. Each mounting hook 86 has a unitary “C” shaped second end 94 that is formed by bending the second end of the mounting hook 86 into a semi-circular section. The radius of the semi-circular section is chosen so that the unitary “C” shaped second end 94 of each mounting hook 86 can securely engage the center distal member 22 of frame 14. The “C” shaped second end 94 terminates in an engagement tab 95, which is sized and shaped to fit into a hole 97 in the center distal member 22.

In an embodiment, the mounting hooks 86 are unitary and formed from sheet metal. One skilled in the art will realize that the configuration of mounting hooks 86 just described could be formed by other methods and use other materials, such as molded plastic.

When the foldable, door-hanging ironing board 10 is in a folded configuration, as shown by FIGS. 1-4, the foldable, door-hanging ironing board 10 can be inserted into shipping container 96. The volume of shipping container 96 is minimized, due to the compact arrangement of foldable, door-hanging ironing board 10 when in its folded position.

Turning now to the operation of the foldable, door-hanging ironing board 10, with the foldable, door-hanging ironing board 10 in the folded position shown by FIGS. 1-4, the foldable, door-hanging ironing board 10 can be stored on a door 100 by engaging the unitary “C” shaped second end 94 of each mounting hook 86 with the center distal member 22 of frame 14 as shown in FIG. 4. This engagement can be accomplished by inserting the engagement tab 95 at the end of the “C” shaped second end 94 of each mounting hook 86 into a hole 97 in the center distal member 22. Then, the unitary “U” shaped first end 88 of each mounting hook 86 are placed over a top edge 98 of the door 100. The weight of the foldable, door-hanging ironing board 10 ensures the engagement of each mounting hook 86 with the top edge 98 of the door 100. The compact nature of the foldable, door-hanging ironing board 10 in its folded configuration, deployed as just described, allows for convenient storage of the foldable, door-hanging ironing board 10, without interfering with the use of the door 100.

With reference to FIGS. 4 and 5, the foldable, door-hanging ironing board 10 can be readied for use from the FIG. 4 position by rotating the ironing board 12 counterclockwise, from the perspective of FIGS. 4 and 5, with respect to frame 14, with sufficient force to overcome the biasing force exerted by torsion springs 72 and 74. As ironing board 12 rotates in this manner, the guide followers 52 of the latch assembly 18 slide within the left track 40 and the right track 42. The rotation of ironing board 12 continues until the rod 48 of the guide assembly 36 engages the lower arm 66 of each of latch pawls 60 and 62 of the latch assembly 18, with the ironing board 12 then in the FIG. 5 position. The engagement of the rod 48 of the guide assembly 36 and the lower arm 66 of each of latch pawls 60 and 62 of the latch assembly 18 is secured by the force provided by the load spring 64 of the latch assembly 18. When the ironing board 12 is deployed in the extended, latched position just described, the lower support member 16 maintains the position of ironing board 12 in response to downward forces generated by a user when ironing clothes on the top of ironing board 12.

After use in the configuration of FIG. 5, the ironing board 12 may be returned to the collapsed position described above and shown by FIGS. 1-4. This can be done by pulling upward on the latch 54, with sufficient force to overcome the bias provided by load spring 64 of the latch assembly 18. The biasing torque of torsion springs 72 and 74 applies rotational force about pivot rod 66 to cause rotation of the ironing board 12 clockwise with respect to frame 18. As ironing board 12 rotates in this fashion, the guide followers 52 of the latch assembly 18 slide within the left track 40 and the right track 42, and the rod 48 of the guide assembly 36 moves away from the lower arm 66 of each of latch pawls 60 and 62 of the latch assembly 18. Once the rod 48 of the guide assembly 36 has moved sufficiently away from the lower arm 66 of each of latch pawls 60 and 62 of the latch assembly 18 such that further engagement between the rod 48 of the guide assembly 36 and the lower arm 66 of each of latch pawls 60 and 62, latch 54 may be released. The torque from the biasing assembly 19 continues to cause rotation of the ironing board 12 until the ironing board 12 is in the collapsed position shown in FIGS. 1-4. The ironing board 12 is thus easily returned to the stored position of FIG. 4. The ironing board 12 remains in this position due to the biasing effect of torsion springs 72 and 74.

Changes can be made in the above constructions without departing from the scope of the disclosure, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
